Question

Four people can paint a fence in three hours. How long would it take six

people to paint the fence, assuming they all work at the same rate? (Hint:
Figure out whether this a direct or inverse proportion.)

Answer 1

4.50 hours it would take 6 people to paint a fence

Answer 2

8

Explanation:

he number of people painting the house and the amount of time it takes are inversely proportional. This means that if we let n be the number of people, and t be the time taken, the product nt is a constant. Since 4 people can paint the house in 6 hours, nt=(4)(6)=24. Therefore, if three people were painting the same house, nt=3t=24, and t=8
